Explorer 1 Observations
I have an Explorer 1 new as of 8/2024. I put it on my timegrapher and dial up indicates 0.0 s/d with an amplitude of 285 beat error 0.0 after a full wind. On the wrist for 12 hours per day and resting dial up for 12 hours per day I have lost 20 seconds in 27 days or .74 seconds per day. Honestly if that remains constant I would be impressed with its performance.
